If 2 objects have the same volume of 10cm3 and object a has a mass of 2 grams and object b has a mass of 4 grams, how do their densities relate to one another?

i need a step by step explanation also. i don’t fully understand the subject. i also need an answer asap. this is due tomorrow and my teacher will not give me extra time even though i was excused.

density of object B is double that density of object A

Explanation:

Density is calculated as follows:

density = mass / volume

then,

density of object A = 2 grams / 10 cm³ = 0.2 g/cm³

density of object B = 4 grams / 10 cm³ = 0.4 g/cm³

The relation between them is:

density of object B / density of object A  =  0.4 / 0.2 = 2

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
